STEAM PLOWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 277,761, dated May 15, 1883.

Application filed December 28, IP82. (No model.)

To all whom it may concern.-

Be it known that we, JOHN D. MALONE and JOSEPH HAMEL, both of Pittsburg, in the county of Allegheny and State of Pennsylva; nia, have invented a new and Improved Steam Plowing-Machine, of which thefollowing is a full, clear, and exact description.

The objectof the invention is to render steamplows practicable by certain improvements, hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of our improved machine, and Fig. 2 is a plan view of therunning-gear. Fig.3 is a longitudinal vertical section, showing the pushers with their operative mechanism. Fig. 4c is also a vertical section, showing the means by which the plows are suspended in gangs. Fig. 5 is a plan view of the mechanism for suspending the plows. Fig. 6 is a detail view, in elevation, showing the means for adjusting the plows.

We mount the boiler a on any suitable frame, I), mounted on the hind carrying-wheels, c, and front carrying and steering wheels, (I, and for the propelling contrivances we use pushers 0, jointed to the hangers f, pivoted on the axes g, and connected to the eccentrics h on the driving-shaft i, which is geared with the crankshaft by the wheel j and pinion We propose to employ two sets of the pushers, one being ahead and the other behind the eccentricshaft, using as many ineach set as may be preferred, and adjusting the eccentrics so as to work the pushers in suitable succession to perform their duty in the best manner. 'By the fiexure of the joints of the said pushers with the hangers fin the forward movements and the straightening of the same in the backstroke, the pushers are enabled to take strong hold on the ground and advance the machine in the measure due to the diflerence of their extension in the forward and backward movements. At the same time they have a lifting effect on the machine calculated to prevent the wheels from sinking in soft ground and thus making greater resistance to the propelling power. The pushers are connected with the eccentrics for being thus operated by suitable rods, j, said rods being attached to the hangers at thejoints with said pushers. They are also connected with bell-cranks k by rods Z, to be lifted oft'the ground, when required, by a lever, m, connected to said bell-cranks bya rod, a.

For applying the steam-power to the turningot the machine shortly around, we have a short shaft, 0, mounted in a hanger, 1), so as to line with the front axle, (1, when turned around to the longitudinal axis of the machine, and geared with the eccentric-shaft by an endless chain, 3, pulleys t, and suitable guide-pulleys, u, to be set-in motion when required, and on this shaft we have a clutch, v, to be shifted into gear with a corresponding clutch, w, on either one of the wheels of the front axle by a lever, 00, when desired, by which the front wheels may be turned by the power of the engine when necessary to use it for the purpose.

We also have the eccentric-shaft geared with one of the hind wheels by an endless chain, 1 and. pulleys z, to be used when required for faster speed along the road, and for turning the machine in crooked roads, which the pushers cannot do.

We also propose to have the crankshaft provided with apulley for being used to drive other machinery by the engine, the machine being stationary and the eccentric-shaftdisconnected.

We propose to suspend the plows a in a gang along the diagonal end frame, I), by means of a short bar or beam, 0, attached to the lower ends of the vertical rods (1, fitted to shift up and down through the frameetimbers; also passing through the adj Listing-bars e, and connected at the upper ends by rods f with levers 9, near their free ends, said levers being pivoted at'the other ends to fulcrums h, and resting on cams i, to be worked by ratchet-wheelsj, pawls 7c, andpawl-levers l, to raise and lower the plows, said ratchet-wheels being provided with suitable holding-pawls, m, to retain them, as required. The cams also have a stud or wrist pin, a, working in ayokc, 0, on the levers, to hold the plows down and prevent them from beingthrustupward in service. The rods cl pass through the regulatingbars 0, which have pivotal connection with the frame atf, and are made to shift up and down the hangers p, and fasten by a set-screw, q, for a variable rest, on which the plows maybe suspended by the collars s", which are adjustable up and down the rods, to vary their position, as may be required. There is to be a ratchet, cam, and lever mechanism to each plow for working the plows independently of each other.

We propose to make the rear extension of the frame on which the plows are mounted detachable, in order that the motor may be used for hauling trucks when required.

' Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a steam-plow, the combination, with the pivoted pushers c, of the hangersf, pivoted to axes g, the pivoted rods j, the eccentriosh, and the shaft z, connecting with suitable operative mechanism, whereby the hanger may be turned, when plowing, by the power of the engine, as described.

4. The combination, in a steam plowing-ma. chine or traction-engine, of a clutch-gear, 0 v, arranged in the longitudinal axis of the machine to connect with the steering-wheels, and being geared with the driving-shaft, substam tially as described.

leys u, and the driving-shaft i, substantially as described.

6. The combination, with the plows a, of 40 the beams c, the rods 61, the bars e, the rods f, the'levers g, fulcrumed at h, the cams i, having lugs or studs n, the yoke o, the ratchet-wh'eelsj,thepawlsk, and thelevers Z,.Whereby the plows may be worked, as described.

7. The combination, in a plowing-machine, of plows a, suspending-rods d, cams Q7, levers g, and ratchet mechanism for operating said cams, substantially as described.

8. The combination of stud or crank pins n and yokes 0' with the levers g, suspendingrods 01, and plows a, substantially as described.

9. The combination of adjusting-bars e and collars s with the suspending-rods d and plows ct, substantially as described.

. 10. The combination, with the regulatingbars 0, having a pivotal connection with the frame, of the hangers p, the set-screws q, .and the collars s, whereby the plows may be suspended adjustably, as described.
